To all whom it may concern-.7

Be it known that 1, CHARLES l KEN wonrrrr, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Baffle Plates, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to battle plates, designed to be used in connection with annealing furnaces or the like.

Among other aims and objects of the invention may be recited the provision of a device of the character mentioned, with a View to compactness, and in which the number of parts are few, the construction simple, cost of production small but efficiency of operation high.

The improvements in details and arrangement of parts will be apparent from an inspection of the accompanying drawings in connection with the description hereinafter contained, and wherein; a preferred embodiment of the invention is disclosed, for the purpose of imparting an understanding of the same.

In the drawings,

Figure 1 is a plan view of a portion of a. floor plate of an annealing furnace or the like and my improved baffle plate, the parts in section being taken generally upon line 1-1 of Fig. 2; and

Figure 2 is an elevation thereof, the parts in section being taken generally upon line 2-2 of Fig. 1.

Referring to the drawings, in connection with which like reference characters indicate corresponding parts; 10 is the floor plate of an annealing furnace or the like having an opening 11 therethrough, which in the drawings shown herein is circular, but may be oval, square, or any other shape, as may be desired, and as adapted to the particular form of furnace with which the baffle plate is used.

My invention is adapted for use in connection with any type of furnace, one of such types being shown in Letters Patent No. 1,388,575, issued to Inc August 23, 1921, the opening 8 in the floor 7 thereof corresponding with the opening 11 in the device herein shown. The floor plate 10 extends over the top of a sealing or other suitable tanlnwithin which is operatively mounted an elevator mechanism, comprising generally a piston cylinder 12 and an elevator platform fined to the top thereof, comprising the base member 13 and the head member 14:. lhis' elevator mechanism is well known in the art and constitutes no part of my present invention.

My ballie plate comprises a bottom plate 15 which is secured between the adjacent parts of the base member 13 and head member 14, a top plate 16 having an opening 17 therethrough of sufiicient size to permit-the lower portion of the head member 14: to

ass therethrough and two band members 18 and 19, which conform to the contour of the bottom plate 15, which is the same as that of the opening 11.

This baffle plate is assembled by filling the open space between the bottom plate 15 and lower plate 16 with asbestos or other heat insulating material, and then by welding or otherwise securing all of the joints between the top and bottom plates and the bands 1'? and 18, so as to form a unitary structure filled with heat resisting material.

In operation, as the elevator moves up and down, it carries with it this ba-flie plate which in its up position forms a closure for the opening 11 in the floor plate and prevents the escape of heat therethrough.

There are minor changes and alterations that may be made within my invention, and I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of the appended claims.

Having described my invent-ion, what I claim as new and desire to secure by Letters Patent, is

1. A baffle plate constructed with a bo tom plate; a top plate having an opening therethrough; a band around the contour of the bottom and top plates; a band within the opening in the top plate and extending to the bottom plate; and heat-resisting material between said plates, said plates being all connected together by welding or otherwise, whereby they become a. single unitary structure.

2. In combination with a furnace having a. plate, with an opening, forming part thereof; an elevator connected therewith;

and having a platform forming a part thereof, which passes through said Opening; and a baffle plate connected with said elevator and forming a heat-resisting closure for said opening when in one of its posi tions.

3. In combination with a furnace having a plate, with an opening, forming part thereof; an elevator connected therewith and having a platform forming a part thereof, which passes through said opening; a baffle plate connected with said elevator and forming a heat-resisting closure for said opening When in one of its positions, said baffle plate being composed of substantially parallel plates separated by a band around the outside of both of said plates, and a second band within an opening in one of said plates and heat-resisting material between all of said plates.

In testimony whereof, I have hereuntoaflixed my signature.

CHARLES F. KENWORTHY,
